Note:

Oracle Linux yum server does not provide equivalent repositories for some channels that are available on ULN. These channels provide non-open source packages.

The kernel source code is available after the initial release via a public git source code repository at https://oss.oracle.com/git/?p=linux-uek3-3.8.git.

If installed, remove the i686 versions of the krb5-server and krb5-server-ldap packages before updating the system, for example:

# yum remove krb5-server.i686 krb5-server-ldap.i686

If you are installing the update on a system on which you have previously installed the Oracle-supported OFED packages, see the following sections for instructions on how to update these packages during the upgrade:

Installing Oracle Linux 7 Update 2 from ULN if the Oracle-Supported OFED Packages Are Already Installed for instructions on how to install the update from ULN.
Installing Oracle Linux 7 Update 2 from Oracle Linux Yum Server if the Oracle-Supported OFED Packages Are Already Installed for instructions on how to install the update from Oracle Linux yum server.

UEK R3 is the default boot kernel for fresh installations of Oracle Linux 7 but the UEK R4 kernel is now also available. For more information, see Unbreakable Enterprise Kernel documentation.

For systems that are running UEK R3 or UEK R4 and are subscribed to the ol7_x86_64_UEKR3 or ol7_x86_64_UEKR4 channel on ULN, or the ol7_x86_64_UEKR3 or ol7_x86_64_UEKR4 repository on Oracle Yum Server, upgrade to the latest UEK release as follows:

Upgrade all packages on the system, including kernel packages.
```
sudo yum update
```
By default, the boot manager automatically enables the most recent kernel version so you do not need to change your GRUB configuration.
Reboot the system.
```
sudo systemctl reboot
```

Important:

Oracle Linux 7 Update 2 updates many major subsystems. To ensure that your updated systems function correctly, reboot them after updating.

Upgrading from Oracle Linux 6

It is possible to upgrade an Oracle Linux 6 system to Oracle Linux 7 Update 2 under the following conditions:

The system meets the minimum installation requirements for Oracle Linux 7 as described in System Requirements.
The Oracle Linux 6 system has been completely updated from the ol6_x86_64_latest channel or ol6_latest repository.
UEK R3 has been installed on the system to be upgraded and is the default boot kernel. Upgrading from UEK R2 is not supported.
No Oracle product stack is present on the system.

Upgrading is supported only for systems that are installed with the Minimal Install base environment.

The following table shows the changes that are applied to any kernels that are configured on the system being upgraded.

Kernel on Original System	Kernel on Upgraded System
RHCK (2.6.32)	RHCK (3.10.0) for Oracle Linux 7 is installed. RHCK (2.6.32) is removed.
UEK R3 (3.8.13)	UEK R3 (3.8.13) for Oracle Linux 7 is installed and made the default boot kernel. The previous version of UEK R3 is removed.

For instructions on how to perform an upgrade, see Oracle Linux 7: Installation Guide.

Installing or Upgrading the Oracle-Supported OFED Packages

The following sections describe how to install or upgrade the OFED packages provided by Oracle, including how to replace the default OFED packages from Red Hat that are present on a system that you have upgraded to Oracle Linux 7 or that you have installed from the Oracle Linux 7 full installation DVD image, the ol7_x86_64_latest channel on ULN, or the ol7_latest repository on Oracle Linux yum server.

For instructions for installing or upgrading OFED packages with UEK R4, see Unbreakable Enterprise Kernel documentation.

Installing Oracle Linux 7 Update 2 from ULN if the Oracle-Supported OFED Packages Are Already Installed

Note:

This procedure assumes that you have registered the system with ULN. See Oracle Linux: Unbreakable Linux Network User's Guide for Oracle Linux 6 and Oracle Linux 7.

To install Update 2 from ULN on an Oracle Linux 7 system on which the Oracle-supported OFED packages are already present:

Subscribe the system to the ol7_x86_64_optional_latest, ol7_x86_64_UEKR3_OFED20, ol7_x86_64_UEKR3, and ol7_x86_64_latest channels on ULN. (By default, the ol7_x86_64_UEKR3 and ol7_x86_64_latest channels are enabled when you register an Oracle Linux 7 system with ULN.)
Edit /etc/yum/pluginconf.d/rhnplugin.conf and add the following lines to the end of the file:
```
[ol7_x86_64_UEKR3_OFED20]
priority=20 
```
Install the yum-plugin-priorities package from the ol7_x86_64_optional_latest channel:
```
sudo yum install yum-plugin-priorities
```
To apply Oracle Linux 7 Update 2 to the system:
```
sudo yum update
```
Any Oracle-supported OFED packages that were already present are updated from the ol7_x86_64_UEKR3_OFED20 channel.
Install Oracle-supported OFED packages such as ibutils, libibcm, librdmacm-devel, librdmacm-utils, librdmacm, opensm, opensm-libs, and srptools from the ol7_x86_64_UEKR3_OFED20 channel as required, for example:
